2、S)檢測羊肉中8種抗真菌藥的方法。羊肉樣品?用含2?0%(體積分?jǐn)?shù))甲酸的乙腈溶液提取后,采用QuEChERS方法凈化。采用AtiantisT3色譜柱(100mm×2?1mm,3μm)進(jìn)行分離,以乙腈?0?1%(v/v)甲酸水溶液為流動相進(jìn)行梯度洗脫,在電噴霧電離源、正離子模式+(ESI)和多反應(yīng)監(jiān)測模式(MRM)下進(jìn)行定性定量分析。實驗比較了不同提取溶劑的提取效果,并優(yōu)化了色譜和2質(zhì)譜的分析條件。結(jié)果表明,8種抗真菌藥物在0?2~50μg/L范圍內(nèi)線性關(guān)系良好,相關(guān)系數(shù)(R)均>0?99;檢出限(LOD
3、)為0?3~3?0μg/kg,定量限(LOQ)為1?0~10?0μg/kg。8種抗真菌藥在低、中、高3個水平下的平均加標(biāo)回收率為70?3%~118?4%,相對標(biāo)準(zhǔn)偏差(RSD)為0?4%~4?3%(n=6)。該方法靈敏高效,回收率優(yōu)良,重復(fù)性好,適用于羊肉樣品抗真菌藥物的有效檢測。關(guān)鍵詞:超高效液相色譜?串聯(lián)質(zhì)譜;QuEChERS;抗真菌藥;羊肉中圖分類號:O658文獻(xiàn)標(biāo)識碼:A文章編號:1000?8713(2018)10?0999?06Determinationofeightantifungaldrug
